BRIEF SUMMARY
Patent Claims
DETAILED DESCRIPTION
[0007] The following detailed description is merely exemplary in
nature and is not intended to limit the disclosure or the
application and uses of the subject matter as described herein.
Furthermore, there is no intention to be bound by any theory
presented in the preceding background or the following detailed
description.
[0008] The present disclosure relates to oxidative color change of
keratinic fibers, in particular hair. When treating keratinic
fibers, in particular hair, with oxidative agents, in particular
with hydrogen peroxide, the pigment melanine, which is endogenous
in the fibers, is destroyed to a certain extent, so that the hair
is or the fibers are necessarily lightened, so that their color
changes even in the absence of a dye. Therefore, the term "color
change" in the sense of the present patent application covers both
lightening and dyeing with one or more dyes.
[0009] Those skilled in the art are familiar with various methods
for changing the color of human hair. In general, either direct
dyes or oxidative dyes are used for dyeing human hair. Oxidative
dyes are formed by oxidative coupling of one or more developer
components with one another or with one or more coupler components.
Coupler components and developer components are also referred to as
oxidative dye precursors. Dyeings achieved with oxidative dyes are
usually referred to as permanent or semipermanent dyeings.
[0010] These agents usually contain hydrogen peroxide as the
oxidative agent. Since hydrogen peroxide has inadequate stability
in storage in an alkaline pH range, oxidative dyes usually consist
of two components that are mixed together immediately prior to use.
One component contains hydrogen peroxide in an aqueous solution or
emulsion, wherein this composition has an acidic pH, usually in the
range of from about 2.5 to about 5.5, to stabilize the hydrogen
peroxide. The second component contains one or more alkalizing
agents in an amount such that the application mixture of the two
components has a pH in the range of from about 8 to about 11. If
the alkalizing preparation does not contain any dye or contains
only small amounts of dye--the latter serves to conceal unwanted
colors that can occur in oxidation of melanine--then it is a
lightener or bleaching agent. However, the alkalizing preparation
may also contain oxidative dye precursors and/or direct dyes and
then the resulting application mixture serves as a dyeing agent. In
addition, there are also dye kits and dyeing methods in which the
application mixture of the two components has a pH in the range of
approx. 6 to about 7.9. However, the dye results with these
so-called "acidic" dyeings often do not achieve the quality
associated with alkaline application mixtures.
[0011] In addition, the alkalizing preparations contain ammonia
and/or monoethanolamine as the alkalizing agent and optionally at
least one oxidative dye precursor, and they have a pH in the range
of from about 8 to about 11.5 measured at about 20.degree. C.
[0012] In addition, the preferred alkalizing preparations are those
that contain, each based on its weight, from about 25 to about 90
wt %, preferably from about 65 to about 85 wt % water, also at
least one 1-alkanol with from about 10 to about 30 carbon atoms,
which is linear or branched and saturated or unsaturated and is
preferably selected from lauryl alcohol, myristyl alcohol, cetyl
alcohol, stearyl alcohol, arachidyl alcohol, 2-octyldodecan-1-ol
and behenyl alcohol as well as mixtures of these 1-alkanols,
especially preferably cetyl alcohol, stearyl alcohol, arachidyl
alcohol, behenyl alcohol and cetyl alcohol/stearyl alcohol
mixtures, in a total amount of from about 2 to about 20 wt %,
preferably from about 2.5 to about 16 wt %, additionally at least
one surfactant in a total amount of from about 0.1 to about 7 wt %,
preferably from about 1.8 to about 4 wt % and optionally additional
ingredients such as organic solvents, chelating agents,
antioxidants and/or reducing agents (to improve the stability in
storage of the oxidative dye precursors), polymers, oils, silicones
and perfumes and optionally at least one oxidative dye precursor
product, wherein all the content data is based on the weight of the
composition (A).
[0013] For oxidative change of hair color, the composition (A) is
mixed with the aqueous oxidative agent preparation as contemplated
herein, referred to as composition (B), wherein the compositions
(A) and (B) are preferably present in a weight ratio A/B in the
range of from about 0.33 to about 3, especially preferably from
about 0.5 to about 2, extremely preferably about 1:1. Compositions
(A) and (B) are mixed in a resealable bottle or a shaker container,
for example, and the resulting application mixture is applied to
the hair to be treated, where it remains for a treatment time of
from about 1 to about 60 minutes, preferably from about 10 to about
45 minutes, especially preferably from about 20 to about 30
minutes, before being rinsed off.
[0014] The object of the present disclosure was to provide an
oxidative dye preparation that is more stable in storage for
oxidative color change agents that are available in the form hair
lightener creams and/or hair dye creams containing fatty alcohol,
wherein the hair lightener and/or hair dye preparations contains
ammonia and/or ammonium hydroxide and/or monoethanolamine as
alkalizing agents and optionally at least one oxidative dye
precursor and have a pH in the range of from about 8 to about 11.5,
measured at about 20.degree. C., with which it is possible to
prepare homogenous application mixtures with a stable
viscosity.
[0015] It has surprisingly been found that aqueous hydrogen
peroxide preparations containing selected 1-alkanols in a total
amount of from about 1 to about 2.8 wt %, selected anionic
surfactants in a total amount of from about 0.05 to about 0.5 wt %,
also dipicolinic acid, 1-hydroxyethane-1,1-diphosphonic acid,
disodium pyrophosphate, benzoic acid and potassium hydroxide in
selected amounts can be adjusted to be stable in storage at a pH in
the range of from about 2 to about 3.8 (20.degree. C.) without the
addition of further stabilizers and can solve the problems
formulated here in a very good manner.
[0016] A first subject matter of the present disclosure is
therefore an oxidative composition for oxidative treatment of hair,

about 80 to about 95 wt %, especially preferably from about 85 to

11.5, measured at about 20.degree. C., wherein all the quantitative
amounts are based on the weight of the composition A; [0125]
producing a mixture of the aforementioned oxidative composition (B)
and the aforementioned composition A, preferably in a mixing ratio
A/B based on the weight in the range of from about 0.33 to about 3,
especially preferably from about 0.5 to about 2, extremely
preferably about 1:1, then immediately thereafter distributing the
ready-to-use agent on the fibers, leaving the agent on the fibers
for a period of from about 1 to about 60 minutes, preferably from
about 10 to about 45 minutes, especially preferably from about 20
to about 30 minutes, immediately thereafter rinsing the remaining
agent out of the fibers and optionally drying the fibers.
[0126] Preferred methods for oxidative color change of keratinic
fibers as contemplated herein are exemplified in that the
aforementioned oxidative composition (B) and the aforementioned
alkalizing composition (A) are mixed together in a weight-based
mixing ratio A/B in the range of from about 0.33 to about 3,
especially preferably from about 0.5 to about 2, extremely
preferably about 1:1.
[0127] With respect to additional preferred embodiments of the
method as contemplated herein, what was said above about the
inventive oxidative compositions and the preferred oxidative
compositions as contemplated herein as well as the alkalizing
compositions (A) used as contemplated herein also applies here,
mutatis mutandis.
[0128] Keratinic fibers, i.e., fibers containing keratin are to be
understood as contemplated herein to be wool, furs, feathers and in
particular human hair. However, the coloring and/or lightening
methods as contemplated herein may also be used in principle on
other natural fibers such as cotton, jute, sisal, linen, silk or
modified natural fibers, for example, regenerated cellulose,
nitrocellulose, alkyl cellulose or hydroxyalkyl cellulose or acetyl
cellulose.
[0129] The ready-to-use coloring agent of the method as
contemplated herein is preferably prepared by combining the
inventive or preferred oxidative composition as contemplated herein
with an alkalizing composition (A) used as contemplated herein in a
resealable container and then mixing them.
[0130] In the subsequent method step, the ready-to-use coloring
agent is distributed on the keratinic fibers. In the method for
color change of human hair, the ready-to-use agent is distributed
directly on the user's head hair. The distribution is preferably
performed manually. To do so, the user removes the ready-to-use
agent from the mixing container, preferably the resealable
container, by scooping or pouring it onto his/her hand and then
distributing it and preferably working the agent into the head
hair. Direct contact between the ready-to-use color change agent
and the user's hands is preferably prevented by using suitable
gloves such as disposable gloves made of latex, for example.
[0131] Then the ready-to-use coloring agent remains on the fibers
to be treated for a period of from about 1 to about 60 minutes. The
period of time is preferably in the range of from about 10 to about
45 minutes, especially preferably from about 20 to about 30
minutes.
[0132] The use temperatures may be in a range between from about 15
and about 40.degree. C. During the remaining time of the agent on
the fibers, a higher or precisely defined temperature may
optionally also be set by external heat source. It is especially
preferable for the color change to be supported by physical
measures. Methods as contemplated herein, in which the application
is supported by using heat, IR and/or UV radiation during the
treatment time, may be preferred here.
[0133] After the end of the treatment time, the ready-to-use
coloring agent and/or the remaining coloring agent is removed in
the last method step by rinsing it out of the fibers to be treated.
To do so, the fibers are rinsed with water and/or an aqueous
surfactant preparation. To do so, hot water at from about
20.degree. C. to about 40.degree. C. and/or a suitable thermally
regulated aqueous surfactant preparation is generally used. This
may optionally be followed by additional treatment steps such as
applying a leave-on conditioner or a rinse-off conditioner, another
coloring step, for example, dyeing or lightening strands, shaping
the hair and/or drying the hair.

[0135] The oxidative compositions E1, E2 and E3 as contemplated
herein presented above as well as the comparative composition (all
oil-in-water emulsions) were prepared by the usual methods
(separate heating of H.sub.2O.sub.2-free water phase and
emulsifier- and surfactant-containing fat phase to approx.
85.degree. C. each, then mixing the hot phases and stirring after
cooling to approx. 20-30.degree. C., adding stabilizers and
H.sub.2O.sub.2 and optionally xanthan, then adjusting the pH). Then
their viscosity (initial viscosity) and pH were measured. The
compositions were then stored for 24 weeks each in the dark at a
temperature of -10.degree. C., +20.degree. C. or +40.degree. C.
Next the viscosities and the pH levels were measured again.
[0136] The oxidative compositions E1, E2 and E3 as contemplated
herein remain stable with respect to the starting values for the pH
and with respect to the starting values for the viscosity, wherein
the deviations from the starting viscosity were all tolerable and
suitable for marketing. The comparative composition underwent
breaking of the emulsion, i.e., a separation of the external water
phase and the dispersed fat phase after 24 weeks of storage under
extremely cold temperature (-10.degree. C.) and high temperature
(+40.degree. C.). Therefore no final viscosities were determined
for the comparative composition. The pH increased significantly in
the course of 24 week storage at +20.degree. C. and +40.degree.
